2A shouldn't make the FETs get hot that quickly if they're being driven properly (they probably are not). You can probably try pulling the rectifiers but it probably won't help if the outputs are out of the circuit. If it does not, install only Q906 and Q907. Do the FETs run cooler?

If not, pull all of the power supply FETs and check the gate drive signal to confirm that both are clean square waves that go to ground cleanly.
